Bbt-68 is a high-purity modified sodium bentonite, which is mainly used in the wet end of papermaking in the paper industry. It plays a role of retention and drainage, improves the water filtration performance of the paper machine, improves its retention rate, and improves the uniformity of the paper. The best effect can be achieved when combined with medium and high molecular weight cationic or non-ionic polymers. The product has high whiteness and is mainly used in the production of white paper to avoid the influence of Bentonite on the amount of fluorescent whitening agent.
